Looking for a manga I can't remember...

I am looking for a sport manga I can't remember!! I don't knw if its n my list, anyways here's what I can remember.

Just as I said earlier its a sprt manga. The part I can remember is they are trying to test their jumps and all. So they put some kind of powder on their hands and will try and jump, to see how high they can jump. So the so called best one jumped, I think. Of course he is the highest. The next one wh will jump looks so weak and all. I think the others left that time so the weak one and another character was left. The so called weak one jumped higher than the best one. I think the two of them was about t leave, when suddenly the weak one jumped............
